Some of you might remember my mad crab hunt a few weeks ago ... and how that crab turned out to be a shell and not really a crab at all. Long story...
Well, it WAS a crab and I found it tonight! Totally by accident, but hey...
My polyps that I severely pissed off by reaquascaping my tank started dying (they turned black and got all mushy) so I asked by husband to break off the part of the rock with the dead polyps on it. When he cracked open the rock, this little guy came out:

I'm not sure if you can see it in these pictures, but he's got white hairs all over his body, so I think he is a
gorilla crab, like you all suggested. What do you think?
